Sorry to report to fellow Lyngdorf 3400 owners, a fuse is a no-go.
Online images of the 3400 with cover off shows what looks like a normal fuse but were too grainy to zoom with clarity. I took the lid off my Lyngdorf 3400 and discovered the fuse is TINY and soldered in place.
The main option I see is to replace the purple fuse in my Zenith 3 with a Master and have it be the only hi-fi fuse in my system. I understand I could try it without risk, but I kinda think it will be some good, some bad compared to the purple. Maybe I’m wrong. Maybe curiosity will get the best of me and I’ll do it….later.
Of course, there is a conditioner I’m interested in. And, if it has a replaceable fuse….I’m in like Flynn. To use an oldy but goody.
